  • un ou plusieurs coussins gonflables délimitant une chambre intérieure,
  • un réservoir de gaz monté sur le support, le réservoir de gaz comprenant au moins un tube autour d'un axe central, le tube présentant une contenance déterminée et au moins un orifice d'évacuation connecté au coussin gonflable, et
  • au moins un dispositif d'actionnement adapté pour faire passer le système déployable entre un état inactif dans lequel le réservoir de gaz est rempli de gaz et le coussin gonflable est dégonflé, et un état actif dans lequel le coussin gonflable est gonflé, le dispositif d'actionnement mettant en communication de fluide l'orifice d'évacuation du tube du réservoir de gaz avec la chambre intérieure du coussin gonflable pour la remplir avec le gaz du réservoir de gaz.
The invention applies in particular to equipment, for example automatic deployment, comprising a support and a deployable system. The deployable system includes:
  • one or more airbags defining an inner chamber,
  • a gas reservoir mounted on the support, the gas reservoir comprising at least one tube about a central axis, the tube having a predetermined capacity and at least one discharge orifice connected to the airbag, and

L'invention s'applique par exemple à une structure gonflable telle qu'une tente dont une armature est constituée par un ou plusieurs coussins gonflables.The invention applies for example to an inflatable structure such as a tent whose armature is constituted by one or more airbags.

L'invention s'applique également par exemple à un équipement de protection destiné à protéger une partie du corps d'un utilisateur dans une situation de risque telle qu'un accident, une chute ou tout autre type de choc. Le support de l'équipement de protection est alors adapté pour être porté par l'utilisateur par exemple dans le cadre d'une activité sportive, récréative, professionnelle ou domestique. L'équipement de protection peut également être destiné à protéger un article dans une situation de risque telle qu'une chute ou tout autre type de choc. Pour prévenir les blessures ou au moins en réduire la gravité dans une application à une partie du corps d'un utilisateur ou bien pour prévenir la détérioration ou au moins en réduire l'étendue dans une application à un article, le système déployable de l'équipement de protection est un système de protection actif dans lequel le dispositif d'actionnement est adapté pour détecter une situation de risque. Le système de protection est alors dans l'état inactif lorsqu'aucune situation de risque n'est détectée par le dispositif d'actionnement, et dans l'état actif lorsqu'une situation de risque est détectée par le dispositif d'actionnement.The invention also applies for example to protective equipment for protecting a body part of a user in a risk situation such as an accident, a fall or any other type of shock. The support of the protective equipment is then adapted to be worn by the user for example in the context of a sporting, recreational, professional or domestic activity. Protective equipment may also be intended to protect an article in a risk situation such as a fall or other type of impact. To prevent or at least reduce the severity of injury in an application to a user's body part or to prevent or at least reduce the extent of damage in an application to an article, the deployable system of the Protective equipment is an active protection system in which the actuating device is adapted to detect a risk situation. The protection system is then in the inactive state when no risk situation is detected by the actuating device, and in the active state when a risk situation is detected by the actuating device.

Un équipement de protection connu du type précité est décrit dans le document WO 2011/148350 .Known protective equipment of the aforementioned type is described in the document WO 2011/148350 .

Dans les systèmes déployables connus, le réservoir de gaz se présente sous la forme conventionnelle d'une cartouche cylindrique.In known deployable systems, the gas reservoir is in the conventional form of a cylindrical cartridge.

De tels systèmes déployables ne peuvent pas être adaptés à diverses applications. En particulier, il est nécessaire de limiter la contenance du réservoir de gaz pour éviter qu'il ne présente un encombrement trop important. De plus, pour limiter les risques que le réservoir de gaz ne blesse l'utilisateur ou ne détériore le support, sa disposition sur l'équipement doit être choisie de manière précise.Such deployable systems can not be adapted to various applications. In particular, it is necessary to limit the capacity of the gas tank to avoid it has a large footprint. In addition, to limit the risk that the gas tank does not hurt the user or damage the support, its provision on the equipment must be chosen accurately.

Les figures illustrent plusieurs modes de réalisation particuliers d'un équipement de protection 2 destiné à protéger une partie du corps d'un utilisateur 1 dans une situation de risque telle qu'un accident, une chute ou tout autre type de choc. L'équipement de protection 2 comprend un support 3 que l'utilisateur 1 peut porter pour couvrir la partie du corps à protéger ou pour être placé à proximité de celle-ci. Comme il apparaîtra de la suite de la description, sans y être limité, l'équipement de protection 2 peut être une veste 15, une ceinture 30, un casque 35 ou un élément de ceux-ci.The figures illustrate several particular embodiments of protective equipment 2 for protecting a body part of a user 1 in a risk situation such as an accident, a fall or any other type of shock. The protective equipment 2 comprises a support 3 that the user 1 can wear to cover the part of the body to be protected or to be placed close to it. As will be apparent from the following description, without being limited thereto, the protective equipment 2 may be a jacket 15, a belt 30, a helmet 35 or an element thereof.

Dans d'autres modes de réalisation, l'équipement de protection pourrait servir à protéger un article dans une situation de risque telle qu'une chute ou tout autre type de choc. Le support est alors conformé pour présenter une surface sur laquelle l'article peut être posé ou fixé par tout moyen approprié ou un logement adapté pour recevoir l'article.In other embodiments, the protective equipment could be used to protect an item in a risk situation such as a fall or other type of impact. The support is then shaped to present a surface on which the article can be placed or fixed by any appropriate means or a housing adapted to receive the article.

L'équipement de protection 2 comprend également un système déployable constituant un système de protection 4 actif.The protective equipment 2 also includes a deployable system constituting an active protection system 4.

Le système de protection 4 comprend :

  • un ou plusieurs coussins gonflables 5 délimitant une chambre intérieure,
  • un réservoir de gaz 6 constitué d'un ou plusieurs tubes 7, 10, 11, 12, 13 s'étendant selon un axe central A, le tube 7, 10, 11, 12, 13 présentant une contenance déterminée et finie et au moins un orifice d'évacuation 8 connecté au coussin gonflable 5, et
  • un ou plusieurs dispositifs d'actionnement 9 adaptés pour détecter une situation de risque et permettre un déploiement, de préférence automatique, du ou des coussins gonflables 5.
The protection system 4 comprises:
  • one or more airbags 5 delimiting an inner chamber,
  • a gas tank 6 consisting of one or more tubes 7, 10, 11, 12, 13 extending along a central axis A, the tube 7, 10, 11, 12, 13 having a determined and finished capacity and at least an exhaust port 8 connected to the airbag 5, and
  • one or more actuating devices 9 adapted to detect a risk situation and allow deployment, preferably automatic, of the airbag or cushions 5.

Tant qu'aucune situation de risque n'est détectée par le dispositif d'actionnement 9, le système de protection 4 est dans un état inactif dans lequel le ou les tubes 7, 10, 11, 12, 13 du réservoir de gaz 6 sont remplis de gaz et le coussin gonflable 5 est dégonflé. En revanche, lorsqu'une situation de risque est détectée par le dispositif d'actionnement 9, le système de protection 4 passe dans un état actif dans lequel le dispositif d'actionnement 9 met en communication de fluide l'orifice d'évacuation 8 du tube 7, 10, 11, 12, 13 du réservoir de gaz 6 avec la chambre intérieure du coussin gonflable 5 pour la remplir de gaz et gonfler le coussin gonflable 5.As long as no risk situation is detected by the actuating device 9, the protection system 4 is in an inactive state in which the tube (s) 7, 10, 11, 12, 13 of the gas reservoir 6 are filled with gas and the airbag 5 is deflated. On the other hand, when a risk situation is detected by the actuating device 9, the protection system 4 goes into an active state in which the actuating device 9 puts in fluid communication the discharge orifice 8 of the tube 7, 10, 11, 12, 13 of the gas reservoir 6 with the internal chamber of the airbag 5 to fill it with gas and inflate the airbag 5.

Le coussin gonflable 5 est de tout type approprié et notamment du type de celui décrit dans le document WO 2011/148350 ou dans le document WO 2014/125368 . Le dispositif d'actionnement 9 est également de tout type approprié et notamment mécanique comme décrit dans le document WO 2011/148351 mais également pyrotechnique, électrique, électronique, électromagnétique ou une combinaison de ceux-ci. Le dispositif d'actionnement 9 est adapté pour détecter une situation de risque de toute manière appropriée et notamment par la détection d'une accélération, d'une rotation, d'un signal, par exemple optique ou électromagnétique, ou autre.The airbag 5 is of any appropriate type and in particular of the type described in the document WO 2011/148350 or in the document WO 2014/125368 . The actuating device 9 is also of any suitable type and especially mechanical as described in the document WO 2011/148351 but also pyrotechnic, electric, electronic, electromagnetic or a combination thereof. The actuating device 9 is adapted to detect a risk situation in any appropriate manner and in particular by detecting an acceleration, a rotation, a signal, for example optical or electromagnetic, or other.

Selon l'invention et comme il apparaîtra plus en détails au cours de la description des modes de réalisation particuliers, le réservoir de gaz 6 est monté sur le support 3 et présente une conformation adaptée à tout ou partie de celui-ci. Pour permettre une telle conformation, le tube 7, 10, 11, 12, 13 du réservoir de gaz 6 est constitué d'un ou plusieurs tronçons tubulaires cintrés le long desquels l'axe central A présente une courbure.According to the invention and as will become more apparent in the description of the particular embodiments, the gas reservoir 6 is mounted on the support 3 and has a conformation adapted to all or part thereof. To allow such a conformation, the tube 7, 10, 11, 12, 13 of the gas reservoir 6 consists of one or more bent tubular sections along which the central axis A has a curvature.

En particulier, le tube 7, 10, 11, 12, 13 du réservoir de gaz 6 comporte une paroi latérale autour de l'axe central A et peut présenter toute section transversale appropriée et notamment circulaire, polygonale, elliptique ou autre. La paroi latérale du tube peut être constituée d'une pluralité de tronçons tubulaires attenants selon l'axe central A. Chacun des tronçons tubulaires présente alors une entrée et une sortie, la sortie de l'un des tronçons tubulaires étant connectée à l'entrée du tronçon tubulaire immédiatement attenant. Outre le ou les tronçons tubulaires cintrés, le tube 7, 10, 11, 12, 13 du réservoir de gaz 6 peut comprendre un ou plusieurs tronçons tubulaires droits le long desquels l'axe central A est rectiligne.In particular, the tube 7, 10, 11, 12, 13 of the gas reservoir 6 has a side wall around the central axis A and may have any suitable cross section and in particular circular, polygonal, elliptical or other. The lateral wall of the tube may consist of a plurality of adjacent tubular sections along the central axis A. Each of the tubular sections then has an inlet and an outlet, the outlet of one of the tubular sections being connected to the inlet tubular section immediately adjoining. In addition to the bent tubular section or sections, the tube 7, 10, 11, 12, 13 of the gas reservoir 6 may comprise one or more straight tubular sections along which the central axis A is rectilinear.

Chaque tronçon tubulaire est un élément de tube réalisé d'un seul tenant. Chaque tronçon tubulaire cintré est alors un élément de tube d'un seul tenant conformé, par déformation ou autre, de telle manière que l'axe central A présente une courbure. Chaque tronçon tubulaire cintré peut être rigide et présenter une conformation permanente ou flexible et présenter une conformation temporaire et évolutive. Un tronçon tubulaire flexible peut alors relier deux tronçons tubulaires rigides, par exemple.Each tubular section is a tube element made in one piece. Each bent tubular section is then an integrally shaped tube element shaped, by deformation or otherwise, so that the central axis A has a curvature. Each bent tubular section may be rigid and have a permanent or flexible conformation and have a temporary and evolutive conformation. A flexible tubular section can then connect two rigid tubular sections, for example.

Des modes de réalisation particuliers de l'invention vont maintenant être décrits plus en détails en relation avec les figures.Particular embodiments of the invention will now be described in more detail in connection with the figures.

Les figures 1 à 3 représentent l'équipement de protection 2 selon un premier mode de réalisation de l'invention comprenant une veste 15 pouvant être portée par l'utilisateur 1 pour se déplacer ou pratiquer une activité sportive ou récréative et notamment pour faire de la moto, de la motoneige, de l'équitation, de l'ULM, du vol en aile delta, du parapente ou autre. En variante, l'équipement de protection 2 pourrait comprendre tout autre vêtement utilisé pour des activités professionnelles ou domestiques présentant un risque de chute ou de choc.The Figures 1 to 3 represent the protective equipment 2 according to a first embodiment of the invention comprising a jacket 15 that can be worn by the user 1 to move or practice a sporting or recreational activity and in particular to ride a motorcycle, snowmobile , horse riding, microlight, delta wing flight, paragliding or other. Alternatively, the protective equipment 2 could include any other garment used for professional or domestic activities with a risk of falling or shock.

La veste 15 comprend le coussin gonflable 5 conformé pour protéger le buste de l'utilisateur 1. Un exemple d'un tel coussin gonflable 5 est décrit dans le document WO 2011/148350 . Sur la figure 1, le coussin gonflable 5 comprend deux portions de protection arrière 16 destinées à s'étendre de part et d'autre de la colonne vertébrale de l'utilisateur 1. Ces deux portions de protection arrière 16 peuvent être reliées au niveau d'extrémités supérieures respectives à une portion de protection supérieure destinée à s'étendre au voisinage du cou de l'utilisateur 1. Par ailleurs, les deux portions de protection arrière peuvent être chacune reliées au niveau d'une extrémité inférieure à une portion de protection avant destinée s'étendre sur le torse de l'utilisateur 1. A cette fin, une portion de protection latérale 17 destinée à s'étendre sur la taille de l'utilisateur 1 peut relier l'extrémité inférieure de la portion de protection arrière 16 à la portion de protection avant.The jacket 15 includes the airbag 5 shaped to protect the bust of the user 1. An example of such an airbag 5 is described in the document WO 2011/148350 . On the figure 1 , the airbag 5 comprises two rear protection portions 16 intended to extend on either side of the spine of the user 1. These two rear protection portions 16 may be connected at respective upper ends to an upper protection portion intended to extend in the vicinity of the neck of the user 1. Furthermore, the two rear protection portions may each be connected at a lower end to a front protective portion for s' extend to the torso of the user 1. For this purpose, a lateral protection portion 17 intended to extend over the size of the user 1 can connect the lower end of the rear protection portion 16 to the portion of the user. front protection.

Le coussin gonflable 5 peut être intégré directement à la veste 15 en étant interposé entre deux couches de la veste 15. En variante, il peut être intégré à une doublure montée de manière amovible sur la veste 15 pour en recouvrir la surface intérieure comme décrit dans le document WO 2014/125368 .The airbag 5 can be integrated directly into the jacket 15 by being interposed between two layers of the jacket 15. Alternatively, it can be integrated with a lining removably mounted on the jacket 15 to cover the inner surface as described in the document WO 2014/125368 .

La veste 15 comprend également une coque 18 présentant une rigidité d'ensemble. Cette coque 18 est, dans le premier mode de réalisation, formée par une dorsale 19. La dorsale 19 comporte une paroi 20 dont la rigidité peut être obtenue par tout moyen approprié, et notamment par un choix de matériaux adapté, une conformation particulière ou une combinaison de ceux-ci.The jacket 15 also includes a shell 18 having overall rigidity. This shell 18 is, in the first embodiment, formed by a dorsal 19. The dorsal 19 comprises a wall 20 whose rigidity can be obtained by any appropriate means, and in particular by a suitable choice of materials, a particular conformation or a combination of these.

La dorsale 19 peut être intégrée directement à la veste 15 ou y être montée de manière amovible. La dorsale 19 est, de préférence, disposée à l'extérieur du coussin gonflable 5 par rapport à l'utilisateur 1. Ainsi la dorsale 19 présente une surface intérieure destinée à être orientée vers l'utilisateur 1, et une surface extérieure opposée à la surface intérieure. Le coussin gonflable 5 et la dorsale 19 sont alors montés sur la veste 15 de telle manière que le coussin gonflable 5 soit en regard de la surface intérieure de la dorsale 19. En particulier, la dorsale 19 est disposée de manière à recouvrir une partie des deux portions de protection arrière 16 ainsi qu'un espace ménagé entre elles et en regard duquel se trouve la colonne vertébrale de l'utilisateur 1. De cette manière, en cas d'accident provoquant le passage du système de protection 4 à l'état actif, la colonne vertébrale de l'utilisateur 1 sera protégée par la dorsale 19 et par les portions de protection arrière 16 interposées entre la dorsale 19 et l'utilisateur 1 pour éviter que la dorsale 19 ne vienne en contact avec la colonne vertébrale de l'utilisateur 1.The dorsal 19 can be integrated directly into the jacket 15 or be mounted removably. The dorsal 19 is preferably disposed outside the airbag 5 with respect to the user 1. Thus the dorsal 19 has an inner surface intended to be directed towards the user 1, and an outer surface opposite the inner surface. The airbag 5 and the dorsal 19 are then mounted on the jacket 15 so that the airbag 5 is facing the inner surface of the dorsal 19. In particular, the dorsal 19 is arranged so as to cover part of the two rear protection portions 16 and a space between them and facing which is the spine of the user 1. In this way, in case of an accident causing the passage of the protection system 4 in the active state , the spine of the user 1 will be protected by the dorsal 19 and the rear protective portions 16 interposed between the dorsal 19 and the user 1 to prevent the dorsal 19 comes into contact with the spine of the user 1.

La dorsale 19 sert de support 3 pour le tube 7 du réservoir de gaz 6. En particulier, le réservoir de gaz 6 est logé dans une épaisseur de la paroi 20 de la dorsale 19. Dans le premier mode de réalisation, un logement 21 ménagé dans la dorsale 19 est adapté pour recevoir, de manière amovible, un insert 22 sous la forme d'un cadre.The dorsal 19 serves as support 3 for the tube 7 of the gas reservoir 6. In particular, the gas reservoir 6 is housed in a thickness of the wall 20 of the dorsal 19. In the first embodiment, a housing 21 arranged in the dorsal 19 is adapted to receive, removably, an insert 22 in the form of a frame.

Le tube 7 du réservoir de gaz 6, par exemple de section circulaire, est constitué par un enroulement plan à spires sensiblement rectangulaires. Le tube 7 comprend des tronçons tubulaires droits et cintrés agencés et dimensionnés pour que le réservoir de gaz puisse être placé à l'intérieur du cadre de l'insert 22. En particulier, le tube 7 comprend une succession de tronçons tubulaires droits et cintrés agencés de telle manière que chaque tronçon tubulaire cintré relie deux tronçons tubulaires droits s'étendant perpendiculairement l'un par rapport à l'autre. Pour limiter l'encombrement du réservoir de gaz 6, l'enroulement peut être jointif, les tronçons tubulaires droits de chaque spire peuvent présenter des surfaces extérieures en contact avec les surfaces extérieures des tronçons tubulaires droits de la spire adjacente.The tube 7 of the gas tank 6, for example of circular section, is constituted by a plane winding with substantially rectangular turns. The tube 7 comprises straight and curved tubular sections arranged and dimensioned so that the gas tank can be placed inside the frame of the insert 22. In particular, the tube 7 comprises a succession of straight and bent tubular sections arranged such that each curved tubular section connects two straight tubular sections extending perpendicularly with respect to each other. To limit the size of the gas reservoir 6, the winding can be joined, the straight tubular sections of each turn may have outer surfaces in contact with the outer surfaces of the straight tubular sections of the adjacent turn.

L'une des extrémités du tube 7 formant l'orifice d'évacuation 8 peut être connectée au coussin gonflable, l'autre extrémité étant bouchée de toute manière appropriée.One end of the tube 7 forming the discharge port 8 may be connected to the air bag, the other end being plugged in any suitable manner.

La figure 4 est une courbe illustrant l'évolution en fonction du temps d'une pression de gaz en sortie de réservoir de gaz 6 selon un mode de réalisation de l'invention et en sortie d'une cartouche de gaz conventionnelle. Le réservoir de gaz 6 a un tube 7 de 14 mm de diamètre et 530 mm de longueur. Le tube est conformé de manière à présenter un tronçon tubulaire cintré de manière à former l'enroulement plan à spires sensiblement rectangulaires représenté sur les figures 1 à 3. La cartouche, quant à elle, a un tube de 30 mm de diamètre et de 140 mm de longueur. Le tube de la cartouche comporte un unique tronçon tubulaire droit.The figure 4 is a curve illustrating the evolution as a function of time of a gas pressure at the gas tank outlet 6 according to an embodiment of the invention and at the outlet of a conventional gas cartridge. The gas tank 6 has a tube 7 14 mm in diameter and 530 mm in length. The tube is shaped so as to have a bent tubular section so as to form the plane winding with substantially rectangular turns represented on the Figures 1 to 3 . The cartridge, meanwhile, has a tube 30 mm in diameter and 140 mm in length. The tube of the cartridge has a single straight tubular section.

Comme il ressort des courbes entre un point A correspondant sensiblement à la détection de la situation d'accident et au passage à l'état actif du système de protection et un point B correspondant au moment où les courbes se croisent, du fait de son plus grand diamètre, de sa plus petite longueur et de l'absence de courbure le long de son axe central, la pression est libérée plus rapidement par la cartouche que par le tube 7 du réservoir de gaz 6 selon l'invention.As is apparent from the curves between a point A corresponding substantially to the detection of the accident situation and the transition to the active state of the protection system and a point B corresponding to the moment when the curves intersect, because of its more large diameter, its smallest length and the absence of curvature along its central axis, the pressure is released more rapidly by the cartridge than by the tube 7 of the gas reservoir 6 according to the invention.

A partir du point B, le tube 7 du réservoir de gaz 6 selon l'invention, qui peut stocker une plus grande quantité de gaz que la cartouche, permet d'atteindre rapidement des niveaux de pression plus élevés.From point B, the tube 7 of the gas tank 6 according to the invention, which can store a larger amount of gas than the cartridge, can quickly reach higher pressure levels.

Or les points A et B ne sont séparés que de 40 ms. Dans une situation d'accident, l'impact intervient généralement plus de 40 ms après le déclenchement du système de protection et le début de la libération du gaz. Le niveau de pression atteint avant ces 40 ms ne revêt donc pas une grande importance. En revanche, le niveau de pression plus élevé atteint au moment de l'impact avec le tube 7 du réservoir de gaz 6 selon l'invention offre une meilleure protection.But the points A and B are only separated by 40 ms. In an accident situation, the impact usually occurs more than 40 ms after the activation of the protection system and the beginning of the release of the gas. The pressure level reached before this 40 ms is therefore not very important. On the other hand, the higher pressure level attained at the moment of impact with the tube 7 of the gas tank 6 according to the invention offers better protection.

Les figures 5 à 7 représentent une variante de l'équipement de protection 2 des figures 1 à 3. Dans ce mode de réalisation, le tube 10 du réservoir de gaz 6 est intégré directement dans une épaisseur de la dorsale 19. En particulier, la dorsale 19 peut comprendre une paroi 25 qui est surmoulée sur le tube 10 du réservoir de gaz 6.
